Welding gas flowmeter used to accurately measure the correct flow rate of welding gases.  

Gauge scale: 0-40 litres per minute.  Inlet Connection 3/8" BSP. 

Flowmeters are designed for use with shielding gases used in MIG/TIG welding applications. The accuracy of the gas flow control is greatly increased by use of a flowmeter fitted to the outlet of an argon-mix or CO2 regulator. It has the added benefit of giving a visual indication of when gas is flowing.
